TOOL FOR REMOVING INCRUSTATIONS IN BOILER-TUBES.

To all whom it may concern Be it known that I, FREDERICK A. PLIM- LEY, a citizen of the United States, residing at Coplay, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Tools for Bemoving Incrustations in Boiler-Tubes, of which the following is a specification.

My invention relates to a manually operated tool for removing deposits or incrustations in boiler tubes; and in such connection it relates to the particular constructive arrangement of the tool for the defined purpose adapted to be revolved within the boiler tube to cut or abrade incrustation or other formations therein effectively, quickly and thoroughly, as well as inexpensively.

The nature, scope and characteristic features of my present invention will be more fully understood from the following description taken in connection with the ac companying drawings, forming part hereof, in which Figure 1, is a vertical central sectional view partly in elevation of a revoluble manually operated tool for removing incrustation from boiler tubes, embodying main fea tures of my said invention. Fig. 2, is a front view of the cutting or abrading head of the tool. Fig. 3, is a view in elevation of the tool and a section of a boiler tube, in central longitudinal section, showing the in crustation formed therein to be removed and operating tool therein to effect the removal of said deposits in the tube; and Fig.4 isacross sectional view on the line 4, 4, of the Fig. 1, of a turbine showing the blades thereof in elevation, said turbine being inclosed within an incasement which abuts against the rear of the hollow head of the tool and the said turbine as arranged splined to a hub forming part of the cap fitted into the head of the said tool.

Referring to the drawings a, in Fig. 3, is a broken, section of a boiler tube in a portion of which is shown the incrusted formation a, to be removed. The tool of my invention consists of a cylindrical cutting or abrading head hollowed out as illustrated in Fig. 1, the head having in the outer and inner peripheries slits fitted with inserts b and 6 of corundum or other preferred readily abrading or cutting material and in the form of oblong blocks or slabs. This head I) is fitted with a cap 6 provided with a hub I). This cap 6 is secured into the Specification of Letters Patent. Patented UB0. 12, 1916.. Application filed March 22, 1916.

rear end of the head I), as clearly shown in Fig. 1. The said cap is provided with a series of concentric channels 6 as clearly shown in Fig. 2, for discharging fluid therethrough. A turbine c, of the type illustrated in Fig. 4, with a series of curved blades or vanes is keyed to the hub 6 of the said cap 72 The said turbine c, is located within a stationary recessed incasement to which at the rear thereof is secured a nipple b the front end of the incasement abutting against the rear end of the hollow head 6, of the said tool. The said incasement b, is provided with a central opening in which is mounted a shouldered bolt d, at one end provided with a nut (Z and the opposite end threaded and screwed into the hub 6 of the cap 6 as clearly illustrated in Fig. 1; the arrangement being such that the shouldered portion of the bolt d, revolves freely in the central bearing of the fixed incasement b", in the operation of the tool by the fluid forced therethrough into the turbine c, to cause it and therewith the head I), to be revolved in unison, independent of the said in casement b. The body of the said incasement 6", is provided with a series of flaring channels 6 as shown, for conducting the fluid in volume under pressure from the hose 0, secured to the nipple b and it into the incasement b, and this fluid flowing under pressure between the curved blades of the turbine c, from the series of channels 6 as clearly shown in Figs. 1 and 4, and thereby the fluid is forced through the series of channels 5 into the hollow of the head Z), to be dispersed or discharged advantageously in a desirable form or condition in the vicinity of the cutting or abrading surfaces of the said head 6, for effective work on the boiler tube deposits or incrustations thereof, first, to soften the same and preparatory to the action thenof the tool by manual pushing of the same through the boiler tube to quickly and effectively remove the deposits or incrustations about the internal wall of the boiler tube in a manner which will be clearly understood from Fig. 3 of the drawings.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is A tool of the character described, comprising a hollow head provided at one end with abrading or cutting means and at the other end with a cap or closure; an incasement to which said head is rotatably se- In Witness whereof, I have hereunto set cured; a turbine splined to said cap and inmy signature in the presence of the two sub- 10 closed insaid incasement; anfd means conscribing Witnesses.
